Method Detail

configure

public void configure()
               throws ConfigurationException

Description copied from class: FixedForwardPipe

checks for correct configuration of forward

Specified by:

configure in interface IConfigurable

Specified by:

configure in interface IPipe

Overrides:

configure in class FixedForwardPipe

Throws:

ConfigurationException

doPipe

public PipeRunResult doPipe(Message message,
                            PipeLineSession session)
                     throws PipeRunException

Description copied from interface: IPipe

This is where the action takes place. Pipes may only throw a PipeRunException, to be handled by the caller of this object. Implementations must either consume the message, or pass it on to the next Pipe in the PipeRunResult. If the result of the Pipe does not depend on the input, like for the FixedResultPipe, the Pipe can schedule the input to be closed at session exit, by calling Message.closeOnCloseOf(PipeLineSession, String) This allows the previous Pipe to release any resources (e.g. connections) that it might have kept open until the message was consumed. Doing so avoids connections leaking from pools, while it enables efficient streaming processing of data while it is being read from a stream.

Throws:

PipeRunException

consumesSessionVariable

public boolean consumesSessionVariable(String sessionKey)

Description copied from interface: IPipe

returns true if the pipe or one of its children use the named session variable. Callers can use this to determine if a message needs to be preserved.

Specified by:

consumesSessionVariable in interface IPipe

Overrides:

consumesSessionVariable in class AbstractPipe

setSessionKey

public void setSessionKey(String string)

Reference to the session variable whose value is to be increased

setIncrement

public void setIncrement(int i)

amount to increment the value. Can be set from the attribute or the parameter 'increment'

Default value

1
